We know this to be rock solid advice for those who aspire to leadership, which starts by being a follower, and which grows through time through the private/self achievement(s), onto public achievement(s), and into the leadership realm, where you climb the stairs from Level 1 to Level 5.

With that in mind, I make it a point to pay forward book recommendations in the blogosphere; reviews are public and I hope they provide you the value-add you need to make the decision to read/invest in the book(s) thereafter.
